winds, visibility, and cloud ceiling heights are generally the elements used to summarize an area’s<br />
climate for airport planning purposes.<br />
The continental type of climate of the <strong>Lansing</strong> area is characterized by larger temperature<br />
fluctuations than areas at the same latitude near the Great Lakes, which have more moderate<br />
temperatures. However, the area seldom experiences prolonged periods of hot, humid weather in<br />
the summer or extreme cold during the winter. Diminished wind speeds or winds that do not<br />
traverse large unfrozen lakes often produce clearing skies and the colder temperatures expected<br />
at continental locations.<br />
The average annual temperature in Clinton County is 47.1 o Fahrenheit. Moderately warm<br />
temperatures dominate summers with July having the average highest temperature at 70.7<br />
degrees. The highest temperature on record was 100 degrees in August of 1964. The last annual<br />
freeze typically occurs in May and the first annual freeze occurs around October. January has the<br />
lowest average temperature at 21.5 degrees. The lowest temperature on record was 25 degrees<br />
below zero in January of 1967.<br />
Precipitation is well distributed throughout the year with the crop season, April through September,<br />
receiving an average of 17.31 inches or 59 percent of the average annual total. Summer<br />
precipitation comes mainly in the form of afternoon showers and thundershowers. The wettest<br />
month is June with an average of 3.50 inches of rainfall, while the driest month is February with an<br />
average of 1.55 inches. Average seasonal snowfall is 51.7 inches.<br />
Prevailing winds in the <strong>Lansing</strong> area are southwesterly, averaging ten miles per hour. The<br />
strongest one-minute wind speed, 63 miles per hour, was recorded in June of 1963. As a result of<br />
the prevailing southwesterly winds, the <strong>Lansing</strong> area does experience some lake effect. However,<br />
this is minimal and essentially limited to increased cloudiness during the late fall and early winter.<br />
1.2.3 Role<br />
Determination of an airport’s classification and role is a function of the Federal Aviation<br />
Administration (FAA) and is used in the process of assembling the National <strong>Plan</strong> of Integrated<br />
<strong>Airport</strong> Systems (NPIAS) and determining airport project funding levels.<br />
1.2.3.1 <strong>Airport</strong> NPIAS Classification<br />
An airport must be included in the NPIAS to be eligible for funding under the <strong>Airport</strong> Improvement<br />
Program (AIP). The NPIAS is prepared by the FAA every two years and identifies public-use<br />
airports considered necessary to provide a safe, efficient, and integrated system of airports to meet<br />
the needs of civil aviation, national defense, and the United States Postal Service. It also takes<br />
into consideration the relationship of each airport to the rest of the transportation system in a<br />
particular area, the forecast of technological developments in aeronautics, and the development<br />
forecast in other modes of transportation. A detailed description of the NPIAS can be found in<br />
Appendix B.<br />
<strong>Capital</strong> <strong>City</strong> <strong>Airport</strong> is listed in the NPIAS as a primary commercial service airport. This descriptor<br />
identifies the <strong>Airport</strong> as one that enplanes more than 10,000 annual passengers.<br />
